We did the adventure mine and sauna in October. It was such a unique experience. We found it by searching for saunas in Sweden and it seemed to be such a one of a kind place. The story of how they created the place is great - the sheer effort and time spent to build such a venue underground. Our sauna guide was so good. Her music and smells felt like another world. The 4 degrees water to swim in was challenging, but rewarding. The food was mostly local and super tasty. Their music venue/ concert hall is another thing altogether. How these guys built it all is another genius altogether.
